If this interests you, have a look at "bibits" as well, its a whole neural network driven ecosystem where each critter has a brain that can evolve over generations. Emergent behaviour like prey/predator species arise over time. Its honestly a really cool tool / toybox for budding scientists.

Even simple neural networks with Hebbian learning can produce surprising emergent behaviors when their inputs and reward systems interact in unexpected ways - I'd be curious to see if the squid develops any quirky preferences or avoidance patterns after extended training.

I have a squid that has become unnecessarily obsessed with playing with poop - throwing it around

Also another that likes to hoard decoration items by pushing them all together into a big pile
